Abstract: This paper focuses on the formulation and validation of a novel perturbation method for the prediction of the forced response of mistuned bladed disks. At the contrary of most previous methods, this approach leads to a ...

Abstract: Component-centric reduced order models (ROMs) are introduced here as small-size ROMs providing an accurate prediction of the linear response of part of a structure (the β component) without focusing on the rest of it (the ...

Abstract: Quantifying effects of system-wide uncertainties (i.e., affecting structural, piezoelectric, and/or electrical components) in the analysis and design of piezoelectric vibration energy harvesters have recently been emphasized. ...

Abstract: This paper focuses on the optimization of intentional mistuning patterns for the reduction of the sensitivity of the forced response of bladed disks to random mistuning. Intentional mistuning is achieved here by using two ...

Abstract: This paper focuses on the development of nonlinear reduced order modeling techniques for the prediction of the response of complex structures exhibiting “largeâ€‌ deformations, i.e., a geometrically nonlinear behavior, ...

Abstract: Component-centric reduced order models (ROMs) have recently been developed in the context of linear structural dynamics. They lead to an accurate prediction of the response of a part of structure (referred to as the β ...

Abstract: The focus of this investigation is first on assessing the validity to structures under inplane forces, in particular near buckling, of the reduced order modeling approach for nonlinear geometric response that has been ...

Abstract: This paper focuses on extending an earlier investigation on the systematic and rational consideration of uncertainty in reduced order models of rotordynamics systems. The current effort concentrates on the consistent ...
